Claim of US Patent No. 9,930,667

1. A method for communication on an unlicensed spectrum in a UE, comprising:receiving a high layer signaling to obtain S and V, wherein the S is L configuration information, the V is N logical information, each of the configuration information comprises a carrier index and a working frequency band, and each of the logical information comprises at least one of the following:
a carrier logical index;
an antenna information, the antenna information comprising a transmission mode; and
a cross carrier information, the cross carrier information comprising a service cell index;
receiving a first DCI, the first DCI comprising a virtual index and a scheduling information; and
receiving a first PDSCH from the working frequency band of a first configuration information in a given sub frame according to the scheduling information of the first DCI;
wherein the first DCI complies with a configuration of a first logical information, the first logical information is that the carrier logical index of the V equals to one logical information of the virtual index of the first DCI; all the working frequency bands of the S belong to the unlicensed spectrum, the L is a positive integer, the N is a positive integer not greater than L, and the first configuration information is one of the following:
the configuration information among the S with the working frequency band including a transmission bandwidth of the first DCI; and
the configuration information among the S with the carrier index being equal to a physical index of the scheduling information of the first DCI.
